heart-sound

It also gives a safety design problem analysis using an electret capacitor microphone to pick-up the heart sound signals.

It consists of a phonocardiogram sensor, a heart sound collecting and processing circuit, and a computer.

The results showed that the first heart sound energy fraction were significantly different in the normal group and the heart murmur group.

Broken heart sound is so crisp, sweet, bent down to pick up a branch in the soil lightly to write a few lines.

The first heart sound is caused by the closure of the atrioventricular valves and so marks the beginning of ventricular systole.

Be quiet, be quiet, call me listen to my own heart sound!

Conclusion The envelope of heart sound is extracted correctly by this method, which is useful for the further analysis.

In view of the above-mentioned, the author presented the project, " A Digitizing Process System for Heart Sound Signal " .

Of fetal cardiac malformations are diagnosed 41 cases of fetal heart sound image analysis, statistics, summary.

Have you ever listen to it carefully, the spring water rushing, hear the wind down, leaves the heart sound.

The operator makes a judgment when that heart sound is muffled.

S3 . The third heart sound (S3, or ventricular gallop) is low-pitched and best heard at the apex with the stethoscope bell.

In the course of recording heart sound, it is inevitable that many kinds of noise will be merged in the main signal.
